Monitoring Methodology and QA/QC Procedure

Instrumentation

2.6 High Volume Samplers (HVS) connected with appropriate sampling inlets were

employed for air quality monitoring. Each sampler was composed of a motor, a filter

holder, a flow controller and a sampling inlet and its performance specification complies

with that required by USEPA Standard Title 40, Code of Federation Regulations

Chapter 1 (Part 50).

HVS Installation

2.7 The following guidelines were adopted during the installation of HVS:

Sufficient support was provided to secure the samplers against gusty wind.

No two samplers were placed less than 2 meters apart.

The distance between the sampler and an obstacle, such as buildings, was at least

twice the height that the obstacle protrudes above the sampler.

A minimum of 2 meters of separation from walls, parapets and penthouses was

required for rooftop samples.

A minimum of 2 meters separation from any supporting structure, measured

horizontally was required.

No furnaces or incineration flues were nearby.

Airflow around the sampler was unrestricted.

The samplers were more than 20 meters from the drip line.

Any wire fence and gate, to protect the sampler, should not cause any obstruction

during monitoring.

Filters Preparation

2.8 Fiberglass filters were used which have a collection efficiency of larger than 99% for

particles of 0.3 μm diameter. A HOKLAS accredited laboratory, Wellab Ltd., was

responsible for the preparation of pre-weighed filter papers for Cinotech’s monitoring

team.

2.9 All filters, which were prepared by Wellab Ltd., were equilibrated in the conditioning

environment for 24 hours before weighing. The conditioning environment temperature

was around 25 °C and not variable by more than ±3 °C; the relative humidity (RH) was

< 50% and not variable by more than ±5%. A convenient working RH was 40%.

2.10 Wellab Ltd. has a comprehensive quality assurance and quality control programmes.






Operating/Analytical Procedures

2.11 Operating/analytical procedures for the TSP monitoring were highlighted as follows:

Prior to the commencement of the dust sampling, the flow rate of the HVS was

properly set (between 1.1 and 1.4 m3/min.) in accordance with the manufacturer's

instruction to within the range recommended in USEPA Standard.

The power supply was checked to ensure the sampler worked properly.

On sampling, the sampler was operated for 5 minutes to establish thermal

equilibrium before placing any filter media at the air quality monitoring station.

The filter holding frame was then removed by loosening the four nuts and carefully a

weighted and conditioned filter was centered with the stamped number upwards, on a

supporting screen.

The filter was aligned on the screen so that the gasket formed an airtight seal on the

outer edges of the filter. Then the filter holding frame was tightened to the filter

holder with swing bolts to avoid air leakage at the edges.

The shelter lid was closed and secured with the aluminum strip.

The timer was then programmed. Information was recorded on the record sheet,

which included the starting time, the weather condition and the filter number (the

initial weight of the filter paper can be found out by using the filter number).

The flow rate of the HVS sampler would be verified to be constant and recorded on

the data sheet after sampling.

After sampling, the filter was removed and sent to the Wellab Ltd. for weighing. The

elapsed time was also recorded.

Before weighing, all filters were equilibrated in a conditioning environment for 24

hours. The conditioning environment should be between 25°C and 30°C and not vary

by more than ±3°C; the relative humidity (RH) should be < 50% and not vary by

more than ±5%. A convenient working RH is 40%. Weighing results were returned

to Cinotech for further analysis of TSP concentrations collected by each filter.

Maintenance/Calibration

2.12 The following maintenance/calibration was required for the HVS:

The high volume motors and their accessories were properly maintained. Appropriate

maintenance such as routine motor brushes replacement and electrical wiring

checking were made to ensure that the equipment and necessary power supply are in

good working condition.

Calibration of the HVS (five point calibration) using Calibration Kit was carried out

every two months. Copies of calibration certificates are attached in Appendix B.

The HVS calibration orifice will be calibrated annually.

Results and Observations

2.13 In the reporting month, 1-hr TSP monitoring was carried out as schedule at each

designated monitoring station on 13 occasions. 24-hr TSP monitoring was carried out

as scheduled at each designated monitoring station on 5 occasions. The monitoring

schedule was updated and is shown in Appendix C. The weather during the monitoring

sessions was mainly sunny and fine.






2.14 All measured 1-hr and 24-hr TSP levels were below the Action/Limit Levels. No

exceedance was recorded in the reporting month.

2.15 The monitoring data and graphical presentations of 1-hour and 24-hour TSP monitoring

results are shown in Appendices D and E, respectively.

3.6 If construction works are extended to include works during the hours of 1900 - 0700,

additional weekly impact monitoring would be carried out during evening and night-

time works. Applicable permits under NCO have been obtained by the Contractor. The

details of the Construction Noise Permit can be referred to Table 5.1.






Monitoring Methodology and QA/QC Procedures

Field Monitoring

3.7 The monitoring procedures are as follows:

The microphone head of the sound level meter was positioned 1m exterior of the

noise sensitive facade and lowered sufficiently so that the building’s external wall acts as a reflecting surface.

The battery condition was checked to ensure good functioning of the meter.

Parameters such as frequency weighting, the time weighting and the measurement

time were set as follows:

- frequency weighting : A

- time weighting : Fast

- measurement time : 30 minutes

Prior to and after noise measurement, the meter was calibrated using the calibrator

for 94.0 dB at 1000 Hz. If the difference in the calibration level before and after

measurement is more than 1.0 dB, the measurement was considered invalid and

repeat of noise measurement was required after re-calibration or repair of the

equipment.

The wind speed at the monitoring station was checked with the portable wind meter.

Noise monitoring was cancelled in the presence of fog, rain, and wind with a steady

speed exceeding 5 m/s, or wind with gusts exceeding 10 m/s.

Noise measurement was paused during periods of high intrusive noise if possible and

observation was recorded when intrusive noise was not avoided.

At the end of the monitoring period, the Leq, L10 and L90 were recorded. In addition,

site conditions and noise sources were recorded on a standard record sheet.

Maintenance and Calibration

3.8 Maintenance and Calibration procedures were as follows:

The microphone head of the sound level meter and calibrator were cleaned with a

soft cloth at quarterly intervals.

The sound level meter and calibrator were checked and calibrated at yearly intervals.

Copies of calibration certificates are attached in Appendix B.






Results and Observations

3.9 In the reporting month, noise monitoring during non-restricted hours was conducted as

scheduled at the designated location on 5 occasions. As advised by the Contractor, no

construction activities will be undertaken during restricted hours as such noise

monitoring during restricted hours was omitted. The noise monitoring schedule is

provided in Appendix C.

3.10 The details of the monitoring results and graphical presentations are shown in

Appendix F. The weather during the monitoring sessions was mainly sunny and fine.

APPENDIX J – Updated Environmental Mitigation Implementation Schedule

(During Construction Phase)

Type of Impact Recommended Mitigation Measures Status

Air Quality Dust mitigation measures stipulated in the Air Pollution Control (Construction Dust) Regulation

shall be incorporated to control dust emission. Notice shall be given to authority prior to

commencing of work

√

Noise Use of quiet PME

N/A

Good Site Practice

Only well-maintained plant should be operated on-site and plant should be serviced regularly

during the construction program;

Silencers or mufflers on construction equipment should be utilized and should be properly

maintained during the construction program;

Mobile plant, if any, should be sited as far from NSRs as possible;

Machines and plant (such as trucks) that may be in intermittent use should be shut down between

work periods or should be throttled down to a minimum;

Plant known to emit noise strongly in one direction should, wherever possible, be orientated so

that the noise is directed away from the nearby NSRs; and

Material stockpiles and other structures should be effectively utilised, wherever practicable, in

screening noise from on-site construction activities.

√

Water Quality The practices outlined in ProPECC PN 1/94 Construction Site Drainage should be adopted to

minimize the potential water quality impacts from construction site runoff and various construction

activities. The recommendation to install perimeter drains to collect site runoff and to properly treat

the runoff by settlement tank/treatment system shall apply to all sites including those for mainlaying

works. Minimum distances of 100 m should be maintained between the discharge points of

construction site runoff and the existing WSD saltwater intake at Tai Po.

√

A discharge licence needs to be applied from EPD for discharging effluent from the construction site.

The discharge quality is required to meet the requirements specified in the discharge licence. All the

runoff and wastewater generated from the works areas should be treated so that it satisfies with all

the standards listed in the TM. Reuse and recycling of the treated effluent can minimize water

consumption and reduce the effluent discharge volume. The beneficial uses of the treated effluent

may include dust suppression, wheel washing and general cleaning. Monitoring of the discharge

quality of treated effluent should be part of the Environmental Monitoring and Audit (EM&A)

programme. Detailed effluent sampling programme for water quality control during construction

phase should be submitted to EPD, AFCD and WSD for approval prior to commencement of the

construction works.

N/A

The construction programme should be properly planned to minimize soil excavation, if any, in rainy

seasons. This prevents soil erosion from exposed soil surfaces. Any exposed soil surfaces should also

be properly protected to minimize dust emission. In areas where a large amount of exposed soils

exist, earth bunds or sand bags should be provided. Exposed stockpiles should be covered with

tarpaulin or impervious sheets at all time. The stockpiles of materials should be placed in the

locations away from any stream courses so as to avoid releasing materials into the water bodies.

Final surfaces of earthworks should be compacted and protected by permanent work. It is suggested

that haul roads should be paved with concrete and the temporary access roads are protected using

crushed stone or gravel, wherever practicable. Wheel washing facilities should be provided at all site

exits to ensure that earth, mud and debris would not be carried out of the works areas by vehicles.

√

Good site practices should be adopted to clean the rubbish and litter on the construction sites so as to

prevent the rubbish and litter from dropping into the nearby environment. It is recommended to clean

the construction sites on a regular basis.

√




Monthly EM&A Report



It is recommended to provide sufficient chemical toilets in the works areas. The toilet facilities

should not be less than 30 m from any watercourse. A licensed waste collector should be deployed to

clean the chemical toilets on a regular basis. The construction workers can also make use of the

existing toilet facilities within the TPSTW as necessary.

√

Notices should be posted at conspicuous locations to remind the workers not to discharge any sewage

or wastewater into the nearby environment during the construction phase of the project.

Implementation of environmental audit on the construction site can provide an effective control of

any malpractices and can achieve continual improvement of environmental performance on site.

√

It is required to register as a chemical waste producer if chemical wastes would be produced from the

construction activities. The Waste Disposal Ordinance (Cap 354) and its subsidiary regulations in

particular the Waste Disposal (Chemical Waste) (General) Regulation should be observed and

complied with for control of chemical wastes.

√

Any service shop and minor maintenance facilities should be located on hard standings within a

bunded area, and sumps and oil interceptors should be provided. Maintenance of vehicles and

equipment involving activities with potential for leakage and spillage should only be undertaken with

the areas appropriately equipped to control these discharges.

√

Disposal of chemical wastes should be carried out in compliance with the Waste Disposal Ordinance.

The Code of Practice on the Packaging, Labelling and Storage of Chemical Wastes published under

the Waste Disposal Ordinance details the requirements to deal with chemical wastes. General

requirements are given as follows:

Suitable containers should be used to hold the chemical wastes to avoid leakage or spillage during

storage, handling and transport

Chemical waste containers should be suitably labelled to notify and warn the personnel who are

handling the wastes to avoid accidents.

Storage area should be selected at a safe location on site and adequate space should be allocated

to the storage area.

√

Marine water quality monitoring should be carried out under emergency condition or during

maintenance of the THEES tunnel to verify the findings of the water quality modelling. It is

recommended that the maintenance of the THEES tunnel, if unavoidable, should be conducted

during winter season or low flow periods and to avoid the “blooming” season of algae (normally from April to June) if practicable. Details of the monitoring requirements are specified in the EM&A

Manual.

Monthly EM&A Report



Waste

Management

Good site

Nomination of approved personnel, such as a site manager, to be responsible for good site

practices, arrangements for collection and effective disposal to an appropriate facility, of all

wastes generated at the site.

Training of site personnel in proper waste management and chemical waste handling procedures.

Provision of sufficient waste disposal points and regular collection for disposal.

Appropriate measures to minimise windblown litter and dust during transportation of waste by

either covering trucks or by transporting wastes in enclosed containers.

Separation of chemical wastes for special handling and appropriate treatment at the Chemical

Waste Treatment Facility.

Regular cleaning and maintenance programme for drainage systems, sumps and oil interceptors.

A Waste Management Plan shall be prepared and this WMP shall be submitted to the Engineer

for approval. One may make reference to ETWB TCW No. 15/2003 for details.

In order to monitor the disposal of C&D materials at landfills and public filling areas, and to

control fly tipping, a trip-ticket system shall be included as one of the contractual requirements

and implemented by an Environmental Team undertaking the Environmental Monitoring and

Audit work. One may make reference to WBTC No. 21/2002 for details.

A recording system for the amount of wastes generated, recycled and disposed (including the

disposal sites) shall be proposed.

√

Waste reduction is best achieved at the planning and design stage, as well as by ensuring the

implementation of good site practices. Recommendations to achieve waste reduction include:

Segregation and storage of different types of waste in different containers, skips or stockpiles to

enhance reuse or recycling of materials and their proper disposal.

To encourage collection of aluminum cans by individual collectors, separate labelled bins shall be

provided to segregate this waste from other general refuse generated by the work force.

Any unused chemicals or those with remaining functional capacity shall be recycled.

Maximize the use of reusable steel formwork to reduce the amount of C&D material.

Prior to disposal of C&D waste, it is recommended that wood, steel and other metals shall be

separated for re-use and / or recycling to minimize the quantity of waste to be disposed of to

landfill.

Proper storage and site practices to minimize the potential for damage or contamination of

construction materials.

Plan and stock construction materials carefully to minimize amount of waste generated and avoid

unnecessary generation of waste.

Minimize over ordering of concrete, mortars and cement grout by doing careful check before

ordering

√

General Refuse

General refuse shall be stored in enclosed bins or compaction units separate from C&D material. A

reputable waste collector shall be employed by the contractor to remove general refuse from the site,

separately from C&D material. An enclosed and covered area is preferred to reduce the occurrence

of 'wind blown' light material.

√

Construction & Demolition (C&D) Material

C&D material generated from the site formation and demolition works shall be sorted on-site into

inert C&D material (i.e. public fill) and C&D waste. In order to minimise the impact resulting from

collection and transportation of C&D material for off-site disposal, the excavated material

comprising fill material shall be reused on-site as backfilling material as far as practicable. C&D

waste, such as wood, plastic, steel and other metals shall be reused or recycled and, as a last resort,

disposed of to landfill. A suitable area shall be designated within the site for temporary stockpiling of

C&D material and to facilitate the sorting process.

√




Monthly EM&A Report



Bentonite Slurry

Bentonite slurries used in construction works should be reconditioned and reused wherever

practicable. Residual used bentonite slurry should be disposed of from the site as soon as possible.

The Contractor should explore alternative disposal outlets for the residual used bentonite slurry and

disposal at landfill should be the last resort.
